BACKGROUND Field of the Art

The disclosure relates to the field of telecommunication and more particularly to the field of advanced radio frequency signal information processing and analysis for telecommunications and other applications.

Discussion of the State of the Art

Most wireless telecommunication requires transmission and reception of radio frequency (radio frequency signal) signals in the radio frequency signal spectrum from frequencies of about 3 kHz to frequencies of about 300 GHz. Mobile, backhaul, consumer, fixed station, and public safety communications, to name a few, rely on frequencies in the radio frequency signal spectrum that are assigned, or allocated, for a particular use. Further, certain frequency bands are licensed to particular users in specified geographical areas.

Due to the proliferation of wireless communication applications, frequency bands for wireless communication in the radio frequency signal spectrum are becoming congested. Efforts continue to be made to increase the efficiency of frequency usage by consolidating and assigning unused or minimally used frequencies, and by reallocating frequencies for use as demand dictates. Additionally, transmitter output power is being reduced to limit the effective area of a transmitted signal so that frequencies can be reused based on geographical diversity. Consumer demand and trends towards high-data rate communications, which requires the use of increasing bandwidth and efficient transmissions methods, drive these innovations. As the complexity of wireless systems naturally increases to support more users in discrete bands, better systematic knowledge of the spectrum environment is needed to ensure proper operation. Indeed, proposed approaches such as dynamic spectrum allocation and cognitive radio techniques for spectrum sharing, to further enhance efficiency of spectrum use, require good knowledge of the spectral environment.

What is needed is a system for analyzing the radio frequency landscape across a broad range of frequencies and over a variety of geographical areas.

Conceptual Architecture

FIG. 1 is a block diagram illustrating an exemplary system architecture overview 100, according to an embodiment. In this overview, a radio frequency signal information processing and analysis system 200 is shown in relation to an array of related computing devices and network components. For example, the radio frequency signal information processing and analysis system 200 may be located on a computing device 110 which has data storage 120 and other computer system components 130. The computing device 110 may be connected to a plurality of collection platforms 140 that gather radio frequency signal information for processing and analysis. The computing device 110 may also be connected to a network 150 comprising other networked computers or systems 160, including but not limited to the internet, and to a variety of networked sources of radio frequency signal information 170. This exemplary system architecture by no means restricts the architecture or configuration of the invention, and a person of ordinary skill in the art will understand that the invention may be implemented using a variety of computer components, computing devices, and network connections.

FIG. 2 is a block diagram illustrating an exemplary radio frequency signal information processing and analysis system 200, according to a preferred embodiment. In this embodiment, the radio frequency signal information processing and analysis system 200 comprises a signal detector 300, a signal confirmer, and a signal analyzer 400. The signal detector 300 receives radio frequency signal information and analyzes it using one or more algorithms to detect possible signals within the data. For portions of the data in which a signal is detected, that portion of the data is forwarded directly to the signal analyzer 500. For portions of the data in which no signal is detected, that portion of the data is sent to storage 120 or discarded. For portions of the data in which a signal is suspected, but where there may be questions about the validity of the signal, that portion of the data is forwarded to the signal confirmer 400 for further analysis. The signal confirmer 400 receives radio frequency signal information comprising suspected signals and analyzes it using one or more algorithms to confirm the existence of suspected signals within the data. For portions of the data in which the existence of a signal is confirmed, that portion of the data is forwarded to the signal analyzer 500. For portions of the data in which the existence of a signal is not confirmed, that portion of the data is sent to storage 120 or discarded. The signal analyzer 500 receives radio frequency signal information comprising at least one detected or confirmed signal, and analyzes it using one or more algorithms designed to provide information about the radio frequency signal landscape.

FIG. 3 is a block diagram illustrating an exemplary signal detector 300, according to an aspect of an embodiment. As signal information is received by the signal detector 300, it is distributed to a demultiplexer 330 and one or more signal algorithms 310 a-n. Each signal algorithm analyzes the data and outputs a result indicating whether a signal was detected (1) or not detected (0). The output of each algorithm 310 a-n is passed to a demultiplexer 330, which, depending on the consensus of the algorithms 310 a-n routes the radio frequency signal information to storage 120, to the signal confirmer 400, or to the signal analyzer 500. In this embodiment, routing to storage 120 occurs where there is a unanimous consensus of the algorithms 310 a-n that there is no signal (00 . . . 0), routing to the signal analyzer occurs when there is unanimous consent of the algorithms 310 a-n that a signal has been detected (11 . . . 1), and routing to the signal confirmer 400 occurs when there is no unanimous consensus of the algorithms as to the detection of a signal (indeterminate). However, a person of ordinary skill in the art will recognize that unanimity of consensus is not required, and that the routing of the data may be based on any combination of outputs from the one or more algorithms 310 a-n, including but not limited to a majority consensus, minority consensus, or even a single indication of the existence of a signal. Further, although this embodiment shows a particular hardware configuration using a demultiplexer 330, a person of ordinary skill in the art will recognize that many configurations of hardware, software, or both, may accomplish the same functionality.

FIG. 4 is a block diagram illustrating an exemplary signal confirmer 400, according to an aspect of an embodiment. As a portion of radio frequency signal information comprising at least one suspected signal is received by the signal confirmer 300, it is distributed to a demultiplexer 440 and one or more signal algorithms 410 a-n and one or more noise algorithms 420 a-n. In this embodiment, the signal algorithms 410 a-n act as positive indicators of the existence of a signal and the noise algorithms 420 a-n act as negative indicators of the existence of a signal. Each signal algorithm 410 a-n analyzes the data and outputs a result indicating whether a signal was confirmed (1) or not confirmed (0). Each noise algorithm 420 a-n analyzes the data and outputs a result indicating whether the portion of data is noise (0) or not noise (1). The output of the set of signal algorithms 410 a-n is passed to an OR logic gate 430 a, which outputs a confirmation of signal (1) if any one of the signal algorithms 410 a-n confirms the existence of a signal, and a non-confirmation (0) otherwise. The output of the set of noise algorithms 420 a-n is passed to another OR logic gate 430 b, which outputs a confirmation of signal (1) if any one of the noise algorithms 410 a-n indicates that the portion of data is not noise (1), and a non-confirmation (0) otherwise. The output of the two OR logic gates 430 a-b is passed to a demultiplexer 440, which passes through the data to the signal analyzer 500 in case of a consensus (11) of the OR logic gates that a signal is confirmed. Otherwise, the data are sent to storage 120 or discarded. In this embodiment, sets of algorithms are used to represent positive indicators and negative indicators of signal confirmation, and the logical conjunction (AND) of the logical disjunction (OR) of the results of each set of indicators is used to determine whether a signal is confirmed. However, a person of ordinary skill in the art will recognize that this particular logical combination is not required, and that the confirmation of the signal may be based on any combination of outputs from any combination of the algorithms 410 a-n, 420 a-n, including but not limited to a majority consensus, minority consensus, or even a single indication of the existence of a signal from a single algorithm. Further, although this embodiment shows a particular hardware configuration using a demultiplexer 440, a person of ordinary skill in the art will recognize that many configurations of hardware, software, or both, may accomplish the same functionality.

FIG. 5 is a block diagram illustrating an exemplary signal analyzer 500, according to an aspect of an embodiment. A signal analysis engine 510 receives signal information from the signal detector 300 and/or from the signal confirmer 400 and analyzes the signal information using one or more algorithms, which may be stored in an algorithm database 520. A person of ordinary skill in the art will recognize that the algorithms may comprise a variety of forms, and that a separate database of algorithms is just one possible form. The algorithms used will depend on the type or types of analyses required for a given purpose, and may include, but are not limited to bin-wise processing, Rayleigh distribution analysis, telecommunication signal classification, receiver anomaly detection, transmitter density estimation, transmitter detection and location, geolocation analysis, telecommunication activity estimation, telecommunication utilization estimation, frequency utilization estimation, and data interpolation. Each of these algorithms is described in further detail below. The results of the analyses may be stored in data storage 120. Machine learning algorithms may also be used in conjunction with, or as part of, these described algorithms.

Some or all of the above-described processing steps may be performed in parallel, either on the same radio frequency signal sample data or on duplicate copies of the original data (that may then be recombined after processing). The system is not limited by the components described, and may include other components, such as signal filters, and additional processing steps such as transforms (fast Fourier transform, wavelet transform, discrete cosine transform, or other related transforms), and additional statistical analyses such as calculation of the mean, median, maximum, minimum, standard deviation, variance, skew, kurtosis, and/or other statistical value of a signal's amplitude, or the log of the amplitude, or of the power in each frequency domain sample.

FIG. 6 is a diagram illustrating a variety 600 of sensor systems and collection platforms for gathering radio frequency signal information. A radio frequency signal information processing and analysis system 200 would be most effective if a broad range of digital radio frequency signal information is collected from a variety of sensor systems and collection platforms with different characteristics. Ideally, the array of sensor systems and collection platforms would comprise a plurality of mobile collection platforms and stationary collection platforms, with each collection platform wherein one of the algorithms used in the is one or more sensor systems. For example, stationary collection platforms may be any ground-based structure such and building or towers, and ideally would be located in geographically diverse locations, and at different altitudes, and with different lines of sight. Ground-based mobile collection platforms (not shown) may be mobile phones or vehicle-mounted. Aerial collection platforms may comprise satellites 606, airplanes 605, cars, or balloons 604, each of might collect data using different instrumentation, from different altitudes, and along different flight paths. Antenna types used by the sensor systems on all collection platforms may comprise directional antennas 601, 603 or non-directional antennas 602.

Detailed Description of Exemplary Aspects

FIG. 7 is a flow diagram illustrating an exemplary algorithm for bin-wise processing 700, according to an aspect of an embodiment. Data “bins” are created by using transforms such as the Fourier transform (and its various implementations such as fast Fourier transform (FFT) or discrete Fourier transform (DFT)), wavelet transform, discrete cosine transform, or other related transforms 701. In a given frequency bin, the values are averaged or summed over a number of transform-domain samples to reduce the variance in the signals and noise levels and thereby allow for low or negative signal-to-noise ratio (SNR) radio frequency signal detection 702. A mean or median value, or other statistical measure in each bin may be determined over a number of transform-domain samples to overcome the effects of a signal that is significantly stronger or weaker than the average 703. A maximum and/or minimum value, standard deviation, variance, or other statistical measure in each bin over a number of transform-domain samples may be determined and used to resolve signals that are continuously present and signals that are intermittent in time 704. Processing may also find the mean, median, maximum, minimum, standard deviation, variance, skew, kurtosis, entropy, and/or other statistical measures, plus the time component for a bin or set of bins in a geographical area, and compare each statistic to the same statistic computed for that bin or set of bins over a large area to identify deviations, identify anomalies, and distinguish signals from noise 705. Bin-by-bin processing may be performed using the average, median, maximum, minimum, standard deviation, variance, skew, kurtosis, and/or other statistical values over a number of transform-domain samples, to reduce the quantity of data in results and expedite processing 706. The number of transform-domain samples in use may be adjusted to increase or decrease time resolution as needed and thereby aid in signal detection 707. Bins may be combined as needed, using a maximum value search or statistical measure to reduce quantity while also detecting the presence of signals 708. Transform-domain samples may also be combined or dropped (for example, using decimation to down-sample the frequency of a signal, using fast Fourier transforms (FFTs) or other transforms, etc.), using combination over time to reduce noise and improve signal detection 709, before finally outputting data for further handling. Although this exemplary bin-wise processing algorithm has been described using particular set of steps in a particular order, it is worth noting that not all steps may need to be used, and the particular order of steps given in this example may not be required, to produce acceptable results, depending on the results required and the nature and quality of the data being processed.

FIG. 8 is a flow diagram illustrating an exemplary algorithm for a Rayleigh distribution analysis 800, according to an aspect of an embodiment. According to the aspect, signals may be detected and classified by finding the Rayleigh distribution of in-phase and quadrature-phase samples 801, comparing the Rayleigh distribution of signals over a frequency band of interest against noise distribution 802, and applying thresholds to isolate signals 803. As with other techniques herein, thresholds may be developed and refined using machine learning and training datasets, improving operation through the application of statistical techniques. According to the “central limit theorem”, a sufficiently large sum of sinusoidal signals will have a distribution that converges around Gaussian noise, and in practice a small number of equal-amplitude signals still retain a distinguishable Kurtosis and thus may be isolate using trained thresholds.

FIG. 9 is a flow diagram illustrating an exemplary algorithm for telecommunication signal classification 900, according to an aspect of an embodiment. This technique may be used to detect, identify, and classify telecommunication signals using image processing techniques in the frequency-domain and/or time-frequency domain. Image processing algorithms may be used in multiple frequency and time resolutions to produce compact datasets 901. These compact datasets may be used as training datasets to train machine learning algorithms to detect, identify, and classify telecommunication signals 902. For example, a 10 MHz LTE signal can be used as training data to refine a model for detection of 10 MHz (or larger) signals in live data. Training may utilize multiple different resolutions for either or both the time and frequency domains, for example to produce more training data from fewer data sets by narrowing the frequency resolution and using smaller portions of bandwidth for each sample. This training may be used to apply machine learning to future datasets in live signal data 903, for example to refine thresholds for other algorithms described herein and to improve signal processing results. Input to a machine learning algorithm may also include features specific to the signal type such as an LTE synchronization symbol based on any one or combination of the primary or secondary synchronization signals or reference signals from one or more antenna ports, or demodulated information block messages. Similarly, other wireless signals may be synchronized or partially demodulated to derive additional features.

FIG. 10 is a flow diagram illustrating an exemplary algorithm for receiver anomaly detection 1000, according to an aspect of an embodiment. When a telecommunication signal is received from a given receiver, the Kurtosis value may be calculated using only the amplitude value of the signal (and not complex values) 1001. This Kurtosis value may then be compared to subsequent signals in question 1002 from the same receiver, and thresholds may be applied to determine whether the signal in question is an artifact of the sensor hardware (i.e., an anomaly) and should be discarded 1003. These thresholds may be refined using machine learning techniques, as described elsewhere. This algorithm may be used to detect spurious signals, aliased signals, and/or signals that are saturating a receiver without contributing additional useful data. Such anomalous signals may be discarded in order to reduce sensor load and improve operations on radio frequency signals, thereby reducing the total amount of data to be processed and cleaning up datasets that are used for various techniques described herein 1004.

FIG. 11 is a flow diagram illustrating an exemplary algorithm for transmitter density estimation 1100, according to an aspect of an embodiment. Depending on the geographical resolution, area covered by each sample (or filled-in sample data from interpolation), or transmitter density, estimating the locations of transmitters may not always be feasible. In these cases, density may be estimated rather than precise locations for transmitters in a given geographical area of interest. In an initial step 1101, measured signal strength data may be received for one or more frequency bands, for example for a specific frequency or group of frequencies, or for interpolated frequency data, and mapped across a geographical area. This mapping may occur regardless of whether there is any information available on transmitter locations. Next, a portion of the geographical area in question may be surveyed 1102, and the number of transmitters in the surveyed area may be counted 1103. The transmitter numbers (and optionally any other observed information such as transmitter types or antenna configurations) may then be correlated with the measured signal strength data 1104, producing a measurement of transmitters-per-signal strength per frequency or group of frequencies. This may then be applied to the remaining (and presumably low-resolution) geographical area 1105 to estimate the transmitter density based on the measured signal strength data.

FIG. 12 is a flow diagram illustrating an exemplary algorithm for transmitter detection and location 1200, according to an aspect of an embodiment. The first step is to examine multiple signal samples taken from different times or look angles at a given frequency or frequencies 1201. Samples may then be examined across multiple frequencies or groups of frequencies 1202, and signals may be correlated in a given geographical area to determine whether a transmitter location has been identified 1203.

FIG. 13 is a flow diagram illustrating an exemplary algorithm for geolocation analysis 1300, according to an aspect of an embodiment. When a set of signal data is received 1301, it may be analyzed using either an iterative method 1302 or a multilateration method 1303. If an initial transmitter time of transmission is known, the iterative method 1302 may be utilized to iteratively fit the timing data for the received signal dataset to the assumed transmitter location. Using the iterative method 1302, for each signal sample in the dataset, a time-of-flight is calculated for each receiving sensor or observation location. This time-of-flight information is then used to determine the range from the signal source to the receiving sensor(s). The multilateral location of the transmitter is calculated from the intersection of the range values. This iterative method 1302 utilizes signal timing information for signals, providing an advantage when multiple sensors are not available; rather than relying on multiple sensors for multilateration, a single sensor may be moved to take samples at different points in time, since the signal transmission timing is known. If the transmitter time of transmission is unknown, the multilateration method 1303 is used instead, which is an expansion of the trilateration method known in the art. In this method, the location of the signal source may be estimated by using additional measurements from the same sensor or by using additional sensors to derive differential ranges. By measuring the time-of-arrival (TOA) for each signal transmission received, and given the known location of the sensor at that time, the range may be calculated for each received signal and therefore arrive at the location of the transmitter. Capturing multiple consecutive timing signals may be used to reduce errors, particularly with weaker signals or where there is a large amount of noise or interference. The timing information can be supplemented with power, phase, and frequency information to potentially increase accuracy. What it is supplemented with (power, phase, frequency) depends on the properties of the sensor (e.g., phase differences require multiple antennas and phase-matched receive paths in the sensor hardware) and the collection platform (e.g., an aircraft or spacecraft with a sensor attached will induce a Doppler shift in frequency with respect to a stationary terrestrial transmitter). In particular in certain signal environments in which power is applied as supplemental information, the estimated error of the calculated transmitter location can be refined using the extent of the observation area and signal strength.

FIG. 14 is a flow diagram illustrating an exemplary algorithm for geolocation analysis using an alternate method 1400, according to an aspect of an embodiment. Geolocation may be determined by receiving signal information over multiple observation locations 1401 and determining the best location estimate based on highest received signal power 1402. The error associated with this estimate may be determined by examining detected signal power and the geographical extent over which the signal is observed 1403. This method of using received signal power can be applied stand-alone, or it can be used to refine timing-based methods.

FIG. 15 is a flow diagram illustrating an exemplary algorithm for telecommunication activity estimation 1500, according to an aspect of an embodiment. According to this technique, telecommunication activity may be estimated within a given frequency band of interest, and may then be compared against the total capacity of that band to identify overall telecommunication usage. For each signal received 1501 within a sample set, the portion of time that the signal energy level is above the noise floor may be estimated, and the frequency of instances where the energy level exceeds the noise floor may be determined 1502. Then a Rayleigh distribution of estimated values may be produced 1503, and correlated to the amount of activity in the frequency band vs. the overall communication capacity of that band 1504.

FIG. 16 is a flow diagram illustrating an exemplary algorithm for telecommunication utilization estimation 1600, according to an aspect of an embodiment. According to this technique, the portion of a given frequency band that is being used vs. the total bandwidth may be estimated, by detecting signals that occupy parts of a defined frequency band and estimating the bandwidth consumed out of the total bandwidth available. First, for each received signal 1601, the signal edges may be detected 1602 by estimating the mean value along the time domain to obtain a single set of data in the frequency domain, and then calculating the gradient. A large magnitude in the gradient indicates the edge of a signal in the frequency domain, so by applying a threshold value edges may be determined for each signal. The bandwidth used by the signal is estimated compared to the overall frequency band 1602, and then the estimated bandwidth of all signals within the band may be compiled to determine the overall bandwidth utilization 1603.

FIG. 17 is a flow diagram illustrating an exemplary algorithm for frequency utilization estimation 1700, according to an aspect of an embodiment. Frequency utilization may be estimated using two methods. The first method 1701 is used where a frequency band has been defined. According to the first method 1701, machine learning algorithms are used to identify clustering of frequencies. The second method 1702 is used where a frequency band has not been defined. according to the second method 1702, a convolutional filter is tuned in time and frequency characteristics to a specific signal type. The filter is convolved over a large time-frequency space, using peaks of the result to identify a signal or signals of interest, from which utilization over the larger frequency can be estimated.

FIG. 18 is a flow diagram illustrating an exemplary algorithm 1800 for sample data interpolation, according to an aspect of an embodiment. Data interpolation is used to fill in gaps in data by combining samples in the time and frequency domains. In the time domain, a variety of factors such as system sample rate, sweep rate, instantaneous bandwidth, platform speed or dynamics (such as altitude or angle changes), or spatial Nyquist sampling, samples may be combined to identify and fill in gaps 1801. Algorithms used to combine the samples may include, but are not limited to, combining data by finding the mean, median, maximum, minimum, variance, skew, and kurtosis for the amplitude, or log of the amplitude, power, or Kurtosis across a period of time. For a moving platform, such as a satellite, aircraft, or other vehicle-mounted sensor, the spatial Nyquist sampling criterion may be taken into consideration as well. Samples may also be combined in the frequency domain 1802, including samples in frequency bins that may not necessarily be adjacent but may be meaningful when combined (for example, frequencies that are related by allocation, such as non-adjacent frequency bands used by the sample mobile network operator). Once the samples are combined, missing data may be filled in by incorporating additional information transmitter location, antenna pattern or configuration, or transmitter power or orientation 1803. For example, a mobile sensor may follow a programmed route (such as a flight path for an aircraft or satellite), but the sensor data may have gaps between route segments. Interpolation may be used to fill in these gaps with additional data, for example using techniques such as in-painting or kriging. Results may be improved through incorporation of transmitter location information, for example using techniques described above or using known (for example, fixed) transmitter locations. This data may then be compared to the data collected by the mobile sensor along its route, filling in gaps where possible. When multiple data points are available already, reverse propagation may be used 1804 to determine missing antenna or transmitter configuration information. Extending this concept, when multiple measured data points are available, this information can be applied to inform and improve propagation modeling 1804.

However, there are many different ways in which memory may be coupled to system 10. Memory 11 may be used for a variety of purposes such as, for example, caching and/or storing data, programming instructions, and the like.

In some aspects, systems may be implemented on a standalone computing system. Referring now to FIG. 20, there is shown a block diagram depicting a typical exemplary architecture of one or more aspects or components thereof on a standalone computing system. Computing device 20 includes processors 21 that may run software that carry out one or more functions or applications of aspects, such as for example a client application 24.

Networks 31 may be implemented using any known network protocols, including for example wired and/or wireless protocols.

In addition, in some aspects, servers 32 may call external services 37 when needed to obtain additional information, or to refer to additional data concerning a particular call. Communications with external services 37 may take place, for example, via one or more networks 31. In various aspects, external services 37 may comprise web-enabled services or functionality related to or installed on the hardware device itself. For example, in one aspect where client applications 24 are implemented on a smartphone or other electronic device, client applications 24 may obtain information stored in a server system 32 in the cloud or on an external service 37 deployed on one or more of a particular enterprise's or user's premises.

In some aspects, clients 33 or servers 32 (or both) may make use of one or more specialized services or appliances that may be deployed locally or remotely across one or more networks 31. For example, one or more databases 34 may be used or referred to by one or more aspects. It should be understood by one having ordinary skill in the art that databases 34 may be arranged in a wide variety of architectures and using a wide variety of data access and manipulation means. For example, in various aspects one or more databases 34 may comprise a relational database system using a structured query language (SQL), while others may comprise an alternative data storage technology such as those referred to in the art as “NoSQL” (for example, HADOOP CASSANDRA™, GOOGLE BIGTABLE™, and so forth). In some aspects, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the aspect. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular aspect described herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art.

Similarly, some aspects may make use of one or more security systems 36 and configuration systems 35. Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with aspects without limitation, unless a specific security 36 or configuration system 35 or approach is specifically required by the description of any specific aspect.
